Title: Method and device for extrusion
Inventor: FUJII SETSUO
IPC: B21C27/04
Filed: 1994-05-26
Abstract: PURPOSE:To enable an extrusion cycle whose degassing process is unnecessary by deaerating air existing between container and billet out of a container before a billet is extruded through a die from the inside of the container, and effectively extruding the billet without containing air. CONSTITUTION:A temporary stop mechanism is provided, by which air existing in a space between extruding container 1 and billet 13, is allowed to temporarily stop just before the container 1 comes into contact with a die 3 before the extrusion of the billet is started. An outer ring 10 is fixed on the end face on the die side of a container tire 2, further, a seal ring which is allowed to freely, movably and undetachably engage in an extruding direction to the outer ring 10, is allowed to abut on a die ring 5. On the other hand, the container is evacuated after arranging a seal block 40 on the end face of the container on an extrusion stem 14 side and making the seal block 40 come into close contact with the outer peripheral surface of the extrusion stem 14. Consequently, an extruded product without the entrainment of air, can be easily attained.

Title: Heat insulating and waterproofing construction work for roof
Inventor: SHIMOMURA TOMOHIKO
IPC: E04D11/02
Filed: 1992-04-06
Abstract: PURPOSE:To prevent a surface member from being separated from a foam plate in a heat insulating board formed by covering both surfaces of the foam plate with the surface members, by drilling holes reaching the inside of the foam plate to release the gas generated in the inside of the plate to the outside. CONSTITUTION:Surface members 12 are stuck to both surfaces of a foam plate 11 to form a heat insulating board 1, and 0.03mm or larger opening-diameter holes H reaching the inside of the foam plate 11 from outside of the surface members 12 are drilled at a density of one hole or more/100cm<2>. Then, the underside of the heat insulating board 1 is coated with an asphalt layer 3 to be laid on a concrete 2, and an asphalt layer 4 and a waterproof sheet 5 are stuck to the upper surface of the heat insulating board 1. When the heat insulating board 1 touches the high temperature asphalt, gas is generated inside of the foam plate 11, but the gas is released to the outside through the drilled holes H serving as the passages from the heat insulating board 1. Thus, separation of the surface member from the foam plate can be further prevented.

Title: Production of semiconductor device
Inventor: KAMEI SEIO
IPC: H01L29/812
Filed: 1980-08-20
Abstract: PURPOSE:To improve the characteristic of a junction type FET formed by ion implantation by adding one of Mg, Be and Zn to a half-insulating substrate in an amount almost equal to that of electrically active Si. CONSTITUTION:Taking account of variations with methods of growing substrates, growth requirements and the like, the amount of Si contained in a half-insulating substrate is determined at a constant value. A P type impurity other than Cr is contained in a melted liquid for forming a substrate in the amount equivalent to the amount of Si to form a substrate. This compensates for Si to concel the possible effect thereby steeping the last transition of the electronic concentration distribution. In other words, Mg is added to a Cr-added CaAs melted liquid which contains the known amount of electrically active Si in the amount almost equivalent to that of Si and then, pulled up. After a mirror finish grinding, Si<+> is implanted into the mixture to make an N layer 12 and further, Si<++> is selectively implanted to make N<+> type source and drain 13 and 14. Then, a heat treatment can highly speed the electronic concentration of the interface between the substrate and the layers 12-14 while enabling the even formation of the interface with a good reproductivity, thus especially improving the gain remarkably. Besides Mg, Be and Zn are effective.

IPC: H04N9/64
Filed: 1987-05-11
Abstract: PURPOSE:To correct the hue of RGB video signals and to enhance the chroma saturation of them through the aid of a simple constitution and a low cost, as well by connection first-seventh resistor groups consisting of one and the same resistance values respectively between the input video signals R, G and B and outputs of the inverse of T, the inverse of G and the inverse of B, i.e., the inverted signals of above-mentioned ones. CONSTITUTION:First resistor groups 7, 8, 9 act as an element to set the chroma saturation and the hue of R, G, B, as they are, and as for the output R, second resistor groups 10, 11, 12 give a component from the G or the inverse of G, and the third resistor groups 13, 14, 15 give the component form the B or the inverse of B, to the output R, and while changing the hue and the chroma saturation of the output R, they offset the change of the signal level of the output R against the output G and the output B. Similarly, fourth resistor groups 16, 17, 18 and fifth resistor groups 19, 20, 21 offset the change of the signal level of the output G against the output B and the output R while changing the hue and the chroma saturation of the output G, and sixth resistor groups 22, 23, 24 and seventh resistor groups 25, 26, 27 offset the change of the signal level of the output B against the output R and the output G while changing the hue and the chroma saturation of the output B. So long as only the values of the first-the seventh resistor groups are the same, a white balance never gets out of order.

Abstract: PURPOSE:To unnecessitate coating with a mold release agent for preventing toner offset and eliminate an ink-jet type image formation failure during fixing by electrophotographic technique. CONSTITUTION:The core bar 61 of a fixing roller 51 having a toner mold release layer 54 is grounded via a diode 62 in normal direction. The core bar 56 of a pressurizing roller 55 is grounded via a diode 63 in its reverse direction. A recording material P after toner image transcription whose back surface has the positive polarity is supplied to a transcribing device 50 with a negative polarity toner T carried on its surface. A positive-polarity charge on the back surface of the recording material P does not escape from a pressurizing roller 55 by means of the diode 63, and the recording material P surface is charged in positive polarity. The fixing roller 51 surface is frictionally charged with a transcribing material P and maintained in negative polarity by means of the diode 62. Thereby, the offset of the toner T against the fixing roller 51 is prevented.

Abstract: PURPOSE:To improve the deterioration of yield, productivity and quality accompanied with the increase of exhaust gas circulating rate by adjusting sintering raw material in a specific oxygen concn. of the circulating exhaust gas from the front part and the rear part of a wind box. CONSTITUTION:The comparatively high oxygen concn. of the exhaust gas from the front part and the rear part of the wind box 11 at the lower part of a pallet 10 for sintering is supplied to the center part of the pallet 10 through hoods 19, 14 by blowers 13, 18 to obtain the improvement of heat efficiency, the reduction of coke quantity and the exhaust gas quantity. In the above exhaust gas circulating sintering operational method, a ventilation index is increased by changing the moisture in pellet, lime quantity, layer height of the raw material or grain size segregation in the layer direction in the range of >=15% oxygen concn. in the exhaust gas. The aim of this increase is predicted from the past data before the actual operation. By this method, the exhaust gas circulating rate can be increased without the deterioration of the productive efficiency.
